EMBROIDERY-FRAME.

To all whom t may concern: v

Be it known that RUDOLPH O'r'ro TRUEB, a citizen of the United States, and a resident of Murray Hill Parli, county of Union, and State of New Jersey, have invented certain new andluseful Improvements in EmbroideryF rames, of which the following is a full, clear, and exact specification.

My invention relates to implements for embroidering fabrics, and consists in devising the herein shown and described improvement in frames for stretching the fabric, whereon the embroidery is to be applied.

The improvement is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of one of the grooved bars of an embroidery frame, to which the fabric, whereon the embroidery is to be applied, is attached;

Fig. 2 is a longitudinal section thereof on line 2 2, indicated in Fig. 1;

Fig. 3 is a cross-sectional view thereof on line 3 3, indicated in Fig. 1;

Fig. 4 is a plan view of a rope, made of twisted strands of soft fibrous material and corresponding in its dimensions with the dimensions of the groove in the bar;

Fig. 5 is a fractional plan view of the improved frame, showing the manner of securing thereto a piece of the fabric, whereon the embroidery is to be applied, and

Fig. 6 is a cross-sectional view on line 6 6, indicated in Fig. 5.

Embroidery frames are usually composed of four bars, two so-called main-bars, provided with means for attaching thereto of the fabric, whereon the embroidery is to be applied, and two side-bars along which one or both of the main-bars are movable and securable thereto in adjusted position, z. e.

at such distance apart as the work requires.

One of the main-bars, designated by the reference letter a is shown in Fig. 1, wherein also the side-bars b and b are shown, inserted in the slots c (see Fig. 2) The mainbar a is shown as it is held in position, relatively to the side-bars b and b, by pins f inserted through the registering perforations f in the main-bar a, and the perforations e in the side-bars. The .other main- -bar (not shown) is similarly equipped, and

in a likewise connected to the side-bars.

The main-bars a are grooved as shown at z Specication of Letters Patent.

and provided with the teethed metallic strips g, secured thereto by screws or nails it. The teeth, or prongs' g" project into the groove e', and are slightly deflected downward as shown in Fig. 6, to avoid the danger of the fabric or the operators hands coming accidentally in lContact therewith.

Embroidery is often requiredvto be ap-` plied to soft, open weave fabrics, and to enable such tender fabrics to be stretched upon the frame and protected against injury by a greater strain upon some part of it7 I have devised the rope fv, corresponding in thickness to the width of the groove z', and which is used to bend or fold the fabric thereon, and then press the rope, with the bend or fold of the fabric thereover, into the Groove 't' and against the prongs g. rlhis rope 'v is made of twisted strands of soft fibrous material, preferably softlyV j Patented Apr. 6, 1920.

Application led August 16, 1919. Serial No. 317,974.

i. The ends of the rope fu may be inserted n into the holes d at the ends of the groove e', and secured thereinl by pushing in the round-headed and blunt-pointed pins y into the bores e as shown in Figs. 1 and 5, respectively.

The use of this rope o also renders the operation of stretching the fabric upon the frame easier, in that it .enables the operator to perform this operation by merely spreading the fabric laterally, laying the rope thereon, bending the-fabric over the rope and then pressing the rope, while holding the edges of the fabric bent over it, into the groove z', and against the prongs g. The same operation is then repeated to attach the fabric to the other mainbar. The lateral spreading of the part of the fabric thus stretched between the main-bars may then, if necessary, be effected by the devices shown and described in the U. S. Letters Patent No. 1,299,873, granted to me April 8,

1919, whereby the fabric is allixed to, and stretched between, the main-bars as evenly as it is feasible to do.

I claim as my invention:

l. In a frame for stretching fabrics, a bar provided `vvith a longitudinal groove, a rowv of prongs arranged along one edge of said groove and eXending into the same, and a rope-like member of soft fibrous material fitting into said groove and engaged by said prongs, whereby a piece of` fabric bent or folded on said member in the groove is securely held therein.

2. ln a frame for stretching fabrics, a bar provided with a longitudinal groove, a row of prongs arranged along one edge of said groove and extending into the same, a ropelike member of soft fibrous material fitting into Said groove and engaged by said prongs,

whereby a piece of fabric bentV or folded on said member in the groove is securely held therein, and means for securing said ropelike member in said groove, Y

3. In a frame for stretching' fabrics, a bar provided With a longitudinal groove and with a hole at each end of the groove, a roW of prongs arranged along one edge of said groove and extending into the same, a ropelike member of soft fibrous material fitting into said groove and engaged by said prongs, whereby a piece of fabric bent or folded on said member in the groove is securely held therein, and inea-ns for fastening the ends of said member in said holes.
